My fiance and I live together and have a daughter. He has two sons, and has equal custody of them so they are with us half the year and with their mom half the year. He has a legal agreement with his ex, stating which child they can claim each year for taxes. However, he was injured and does not receive income now, so I am sole earner. Can I claim his son as a dependent since I supported them, he lived with us an equal amount of the year, and his father is legally entitled to claim him?
Do I need to file a form showing the court agreement?
Can I still claim head of household, even though we are unmarried, since he is not legally my stepson? I am also claiming my daughter as well, so planned to file as head of household.
